HELP someone please!!!! i dont understand

Answer:

x = 65.03°

Step-by-step explanation:

To solve for x, we have to apply trigonometric ratio.

Recall: SOH CAH TOA

From the diagram, we know the following:

Reference angle = x

Hypotenuse = 45

Adjacent = 19

Since we know the Hyp and Adj, we would apply CAH, which is:

Cos x = Adj/Hyp

Plug in the values

cos(x) = \frac{19}{45}

x = cos^{-}(\frac{19}{45})

x = 65.0250346°

x = 65.03° (nearest hundredth)
